Phần này là streaming video, nhưng điều này liên kết bên không phải là một bộ phim cũ, Jennifer Beals - xin lỗi. Thay vào đó, tôi muốn nói một chút về Flash Video. Khá nhiều các đoạn video mà bạn xem trên Net những ngày này được cung cấp trong định dạng Flash (FLV) Video - | Chapter 8 Netbook Fun and Games 133 Flash dance This section is about streaming video but this sidebar isn t a link to the old Jennifer Beals movie sorry.
